Hi There!
Exponents are used in math so its easier to multiply. For example if you have to do 8 * 8 * 8 * 8 * 8 * 8 * 8 * 8, then to make it easier to multiply you could change into the exponent form
that is what exponents are used for in math
Hope This Helps :)

So you would write this
If you cannot draw that on your computer, then I would stick to saying "segment AB".
